Abstract

Description

We report measurements of the phase of the conductivity, $ϕ_σ\equiv arg(σ)$, in the normal state of a $Bi_{2}Sr_{2}CaCu_{2}O_{8+δ}$ (BSCCO) thin film from 0.2-1.0 THz. From $ϕ_σ$ we obtain the time delay of the current response, $τ_σ\equivϕ_σ/ω$. After discovering a systematic error in the data analysis, the extracted $τ_σ$ has changed from that reported earlier. The revised data is shown in the sole figure below. Analysis and discussion of these data will follow.
